^aAll adjusted hazard ratios are fully adjusted for the other variables in the model, in addition to gender, major histology (Burkitt's, follicular, lymphoblastic, diffuse large B-cell, anaplastic, and other/unknown) and diagnostic year. Results for individuals with race/ethnicity other than what is listed (N = 40), or cases missing data for stage (N = 202) or chemotherapy (N = 42) were excluded from analysis.

*Test for significance at α = 0.05.
